Description

Technical Field

[0001] The utility model relates to the field of welding devices, and more specifically, to a positioning welding device for the production of air conditioner collector pipes. Background Technique

[0002] The main function of the air conditioner collector pipe in the air conditioner is to collect all the gases in the evaporator, and then connect to the outdoor unit through the collector pipe, so as to play a role in circulation. Since the air conditioner collector pipe needs to be bent during air conditioner assembly, most of the existing air conditioner collector pipes are provided with a section of corrugated pipe. The main pipe of the collector pipe and the corrugated pipe are generally processed separately, and then the two are connected into one body by welding.

[0003] During the welding process of the collector pipe, the welding point is prone to deviate from the position of the welding torch, resulting in damage to the welding strength, which is not conducive to ensuring the welding efficiency of the collector pipe. Therefore, it is necessary to design a positioning welding device for the production of air conditioner collector pipes to solve the above problems. Content of the Utility Model

[0004] 1. Technical Problems to be Solved

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a positioning welding device for the production of air conditioner collector pipes, which can generate a positioning signal by using a contact sensor when multiple clamping bases are sequentially moved to the position below the L-shaped vertical plate, so that the welding operation of the air conditioner collector pipe processing body is more accurate and not prone to deviation, thereby ensuring the welding efficiency of the air conditioner collector pipe processing body.

[0006] Technical Solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A positioning welding device for the production of air conditioner collector pipes includes a processing turntable and a clamping base. The upper right side of the processing turntable is fixedly connected with an L-shaped vertical plate. The front end of the L-shaped vertical plate is fixedly connected with a pair of circular horizontal plates. A self-return damping rotating shaft is installed between the two circular horizontal plates. The output end of the self-return damping rotating shaft is fixedly connected with a horizontal rotating rod. One end of the clamping base close to the horizontal rotating rod is provided with a vertical slot. Both the upper and lower sides of the rear inner wall of the vertical slot are fixedly connected with springs. The outer ends of the springs are fixedly connected with inner pushing vertical bars. The middle part of the inner side wall of the vertical slot is provided with an inner groove. One end of the inner pushing vertical bar close to the inner groove is fixedly connected with a contact sensor.

[0009] Furthermore, the contact sensor cooperates with the inner groove.

[0010] Furthermore, welding torches are fixedly connected to the four corners of the lower inner wall of the L-shaped vertical plate, and a plurality of clamping bases are annularly and fixedly connected to the outer side of the upper end of the processing turntable.

[0011] Further, an air-conditioning collecting pipe processing body is clamped at the upper end of the clamping base.

[0012] Further, the output ends of multiple welding torches are matched with the connection parts of the air-conditioning collecting pipe processing body.

[0013] Further, the processing turntable rotates clockwise, and a dust suction port is fixedly connected to the lower inner wall of the L-shaped vertical plate.

[0014] Further, a suction pipe is fixedly connected to the upper end of the dust suction port, and a pump is externally connected to the suction pipe. Beneficial effects

[0015] Compared with the prior art, the advantages of the present utility model are as follows:

[0016] (1) When multiple clamping bases are sequentially moved to the position below the L-shaped vertical plate in this solution, the horizontal turning rod can contact and squeeze the inner pushing vertical bar outside the clamping base, so that the inner pushing vertical bar is pushed inward. When the contact sensor is pushed into the inner groove, an accurate positioning signal can be generated. When the rotation position of the processing turntable has an error and does not completely enter the space below the L-shaped vertical plate, the horizontal turning rod does not contact the inner pushing vertical bar, and the contact sensor does not generate an accurate positioning signal, prompting the staff to come and adjust, so that the welding operation of the air-conditioning collecting pipe processing body can be more accurate, not easily deviate, and thus ensure the welding efficiency of the air-conditioning collecting pipe processing body.

[0017] (2) And when multiple welding torches process the interfaces of the air-conditioning collecting pipe processing body, a large amount of smoke will be generated, affecting the workshop environment. Therefore, a dust suction port can be set below the L-shaped vertical plate directly above the air-conditioning collecting pipe processing body, and the processing dust can be adsorbed by the suction pipe through an externally connected pump, which is beneficial to ensuring the workshop environment.

[0027] Embodiment:

[0028] Please refer to Figure 2-4, A positioning and welding device for the production of an air conditioner collector pipe, including a processing turntable 1 and a clamping base 7. On the upper right side of the processing turntable 1, an L-shaped vertical plate 2 is fixedly connected. At the front end of the L-shaped vertical plate 2, a pair of circular horizontal plates 4 are fixedly connected. Between the two circular horizontal plates 4, a self-return damping rotating shaft 5 is installed. The output end of the self-return damping rotating shaft 5 is fixedly connected to a horizontal rotating rod 6. One end of the clamping base 7 close to the horizontal rotating rod 6 is provided with a vertical slot 11. On the upper and lower sides of the rear inner wall of the vertical slot 11, springs 13 are fixedly connected. The outer ends of the springs 13 are fixedly connected to inner pushing vertical strips 8. In the middle of the inner side wall of the vertical slot 11, an inner groove 10 is provided. One end of the inner pushing vertical strip 8 close to the inner groove 10 is fixedly connected to a contact sensor 12.

[0029] Please refer to Figure 2-4 , The contact sensor 12 cooperates with the inner groove 10. At the four corners of the lower inner wall of the L-shaped vertical plate 2, welding torches 3 are fixedly connected. On the outer ring of the upper end of the processing turntable 1, a plurality of clamping bases 7 are fixedly connected in a ring. An air conditioner collector pipe processing body 9 is clamped on the upper end of the clamping base 7. The output ends of the plurality of welding torches 3 are matched with the connection part of the air conditioner collector pipe processing body 9. The processing turntable 1 rotates clockwise. A dust suction port 14 is fixedly connected to the lower inner wall of the L-shaped vertical plate 2. The upper end of the dust suction port 14 is fixedly connected to a suction pipe 15. The suction pipe 15 is externally connected to a pump.

[0030] Please refer to Figure 1-4 , In this solution, when multiple clamping bases 7 are successively moved to the position below the L-shaped vertical plate 2, the horizontal rotating rod 6 can contact and squeeze the inner pushing vertical strip 8 outside the clamping base 7, causing the inner pushing vertical strip 8 to be pushed inward. When the contact sensor 12 is pushed into the inner groove 10, an accurate positioning signal can be generated. After the air conditioner collector pipe processing body 9 on the clamping base 7 is processed by the welding torch 3, the clamping base 7 continues to rotate clockwise. After receiving the thrust of the horizontal rotating rod 6, the horizontal rotating rod 6 generates a rotational force using the self-return damping rotating shaft 5, enabling the clamping base 7 to move smoothly and then the horizontal rotating rod 6 to reset using the self-return damping rotating shaft 5. When there is an error in the rotation position of the processing turntable 1 and it does not completely enter the space below the L-shaped vertical plate 2, the horizontal rotating rod 6 does not contact the inner pushing vertical strip 8, and the contact sensor 12 does not generate an accurate positioning signal, prompting the staff to come and adjust. This can make the welding operation of the air conditioner collector pipe processing body 9 more accurate and less likely to deviate, thereby ensuring the welding efficiency of the air conditioner collector pipe processing body 9. Moreover, when multiple welding torches 3 process the interface of the air conditioner collector pipe processing body 9, a large amount of smoke will be generated, affecting the workshop environment. Therefore, a dust suction port 14 can be set below the L-shaped vertical plate 2 directly above the air conditioner collector pipe processing body 9, and the processing soot can be adsorbed by the suction pipe 15 through an externally connected pump, which is beneficial to ensuring the workshop environment.

[0031] The above are only the preferred specific embodiments of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and its improved concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
